I can understand your concern.
The prescription provided by your doctor is completely apt. Whatever products ( emollients and soap) she has suggested are mild and hypoallergenic. I presume candiderma application over face was suggested for some fungal infection
or seborrheic dermatitis
and it led to some kind of irritant reaction over face. So stop using the same over your face, you might need to apply a mild steroid
cream to settle redness
and burning sensation of skin.
No doctor can predict whether a particular medicine would suit or cause an irritant reaction in patient. So I would advise have trust in your doctor and visit her again. She would advise you the right treatment to treat the irritant reaction.
Hope that answers your query. Take care.
